Similar problem, going on eons.
Few years ago read where the brachilius muscle in the forearm and how it is shaped and formed and attached to other muscles really has an effect on the bicep in a major way.
I can lift pounds and intensity and volume, and all different ways, yet nothing.
Reccomendation was 45 degree on bench facing forward, apparently this position takes the forearm out of equation, obviously then be strict and squeeze, my pounds went down by 60% easy and got incredible burn, kinda like warps preacher curl thing.
Maybe give it a shot.
Overall bi's are my worst bodypart, just not a big grower not matter waht.
good luck
